K&N 33-2438 Air Filter Product Reviews

Thursday, February 22, 2018 - Part 33-2438
I have used K&N air filters for almost 20 years. The price of one K&N filter is equal to about three paper-factory filters. The additional plus is the money you same with the added fuel mileage. I figured it takes about 8-10 tanks of fuel to pay for most air filters. I’m not an accountant but I know the K&N saves me money. Reagan Houston, Texas

I received the air filter for my 2013 FJ Cruiser and was impressed with how well it is made. Installation was a breeze and the K&N air filter is a perfect fit.  Your website is so user friendly and made my purchase easy.  I noticed an improvement in acceleration due to better air flow into the engine.  I will recommend your products to our FJ club in San Diego.  Keep up the great work.  Thank you.  Daniel Foxworthy.

The filter shipped fast and fit perfectly. I plan on keeping this vehicle for a long time so I like the idea of not having to buy another air filter for it again. I have had K&N filters in many of my vehicles over the years and they have always been high quality.

I have 4 cars but can't afford to buy air filters, cabin filters and oil filters for all 4 cars. If they have sales on the filters let me know. Thank you, Larry Olsen
